My 1970 280SE, after warming up, runs progressively worse until
eventually it stalls out. After stalling, it won't even start up. If
you let it cool down for several hours, you can again drive the car
for a short distance before the problem again happens. Recent points,
plugs, wires, distributor cap.
At cool temperature, the car sputters if you hit the accelerator hard.
Not sure if this performance problem is related to the stalling.
Any thoughts on what the problem might be, or how to diagnose, would
